Does anyone out there use Lysol in the cat's litter pan? I've been using vinegar and water to clean Cassie's litter pan, but I wonder if I should be using something with a disinfectant. My sister used to use Lysol with her cats. I remember her rinsing and rinsing and rinsing the box. That's why I've been using vinegar. Is there something more organic I can try? How often does anyone replace the pan itself? She's so funny ... I empty, clean, refill it, go down to the Dumpster with the "old" litter and usually, within 10 or 15 minutes I hear her in there digging and pawing. Silly kitty
